This study presents the first mitochondrial genome (16,342 bp) of the invasive species Fang et al., 2022, revealing a conserved Capitata-like gene arrangement, comprising 13 protein-coding genes, two rRNA genes, and two tRNA genes, along with a duplicated pseudo- fragment. Phylogenetic analysis robustly supported and as reciprocally monophyletic mitogenome lineages, forming a robust clade sister to . This topology supports the morphological dichotomy between the -like lineage (filiform tentacles, gastric pouches) and -like species. These findings contribute a critical genomic resource for advancing the understanding of medusozoan phylogeny.
本研究展示了入侵物种Fang等人于2022年发现的首个线粒体基因组（16342 bp），揭示了一种保守的类似头状水母的基因排列，包括13个蛋白质编码基因、两个rRNA基因和两个tRNA基因，以及一个重复的假片段。系统发育分析有力地支持了[两个物种名称]作为相互单系的有丝分裂基因组谱系，形成了一个与[另一物种名称]姐妹的强大分支。这种拓扑结构支持了类似[某物种]谱系（丝状触手、胃囊）和类似[另一物种]物种之间的形态二分法。这些发现为推进对水母动物系统发育的理解贡献了关键的基因组资源。
